Key can opener



1-1. MOCK KEY CAN OPENER Filed Dec. 14, 1929 June so, 1931. I

Patented 1...... so, 1931' key can openers and moreparticularly to im- 7 provements in the keys-by which the ordinary type of'food containercans are opened and in the parts of the can co-operatingcwith the key in the opening of same. A principal object of my invention is the provision of an improved key can opener in which positive means are present so that the loopening or ripping. of the oan will always take place in a pre-determ;ined= direction v along the lines of scoring on the'body' of the.

can.

Further objects of my invention are the 1 provision of the key and co-operating of the" can by which the key willbe more firmly held than in'the present type ofopener and in which the key will be held at alltimes at Y a fixed angle .to the line of opening of the 02111. Further objects of my invention will be apparent from the specification and drawings in which,

with a tongue B and claim no novelty either in the form of can or tongue, excepting that I I have added tothe tongue aslot C which is parallelv to the edgethereof andat right angles to the direction toward which thekey is tongue. In this way ELPOSllZlVGgIlP is ob- Fig. 2 is a perspectiveview of animproved can a conventional can A turned. Thetop of thecan' Aisprovlded j I withfscoringlinesconnecting with the tongue I c, C, the' top ofthe can A being tearable along such: scoring lines.

In Fig. 2- is shown a perspective view of at my improved key which; is the sameas the conventional key now in use except forfthe projection D which is adapted to fit into and -,positively'grip theslot C. By making the projection. D fit the slot C, the key D when (6O turned in thedirection of the line ofscoring will tend to keep its axis at right angles to the directionin which such key. is turned and 1 will also prevent the key from slipping off the tained "upon" the tongue which permits the opening of the can with certainty at all times.

I have shown this improvement adapted .to 7

a can in which thetop is detachable but it is evident that the same improvement may be 7a" usedwhere the can is opene'don the side. It 1s also apparent that modifications in the tongue and in the key itself as ilitlleflfOI'm i of the projections or'teeth used to grip the 1 1' tongue, maybe made without departing from i the spirit of my invention. V

Having fully described my invention what I claim is V o 1. A key'for opening a rip strip can, said. key being provided with an "aperture, the in- {86' 'terio'r of sai d'aperture being provided with engaging'means adapted .to engage and grip the tongue of a rip strip can.

In combination, a key for opening a'ripl strip can, said key being provided with an aperture, said key having. engaging means adjacent said aperture adapted to engage and grip the opening in the tongueiof a rip strip can.

. 4. In combination, a key for opening a rip f p strip can, said key being provided withian aperture, said aperture being provided with engaging means adapted'to engage and gri the slot'in the tongue of a rip strip can. 1

5 A key for opening a rip strip can, said 1 19. j

key bein provided with an aperture, the interior of said aperture being provided with engaging means adapted to engage reciprocal engaging means on a rip strip can.

6. In a rip strip can, a tongue on said can having a slot therein and a key provided with engaging means adapted to engage said slot for opening said can.
